The new gift comes in the form of 10 bonus, which is enough to redeem for a free order of Garlic Knots, Cheesesticks, or a giant Chocolate Chip Cookie. They can also be combined with existing points to get a pizza.
You'll have some time to use the bonus points as well as they arrive in an email as a promo code during the first week of your birthday month and don't expire until the last day of your birthday month.
Do keep in mind that you actually have to be signed up to Papa Rewards to get the points (it's free to join) and you have to opt in to emails for them to arrive in your emailbox. While the bonus points eventually expire, normal points earned in the program do not.
